To (LZZ whom it may concern:

Be it known that I, WILLIAM W. PRICE, a citizen of the United States,residing at Dayton, in the county of Montgomery and State of Ohio, haveinvented certain new and useful Improvements in Pi e-Ooupling Rings; andI do declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the figures of reference marked thereon,which form a part of this specification.

This invention relates to new and useful lmprovements in coupling-ringsby means of which the ends of pipes are joined.

The invention consists in the particular construction of the ring, whichis made from sheet steel by means of suitable dies which cooperate togive the ring the form substantially as is herein illustrated.

The object of the invention is to simplify the manufacture as well as toexpedite the manufacture of these devices and to provide a ring of theabove type which possesses a high degree of durability or lastingqualities in addition to numerous other advantages possessed by said rinPreceding a detail description of the invention reference is made to theaccompanying drawings, of which- Figure l is a cross-sectional view ofmy improved pipe-coupling ring on the line a: a: of Fig. 2 Flg. 2 is atop plan view of the ring.

In a detail description of the invention similar reference charactersindicate corresponding parts.

The pipe-c0upling ring which forms the subject-matter of thisapplication is essentially constructed of pressed steel or platesteel ofsuitable thickness, depending upon the diameter of the ring. The saidring is pressed from a suitable blank of plate-steel y means of suitabledies and punches to give it the requisite formation. This formationconsists of an annular ring or member, the greatest diameter 1 by awall/i, which is slightly tapering and of which is inclosed terminateson one side in an inwardly-extending slightly-tapering wall 3, which inturn terminates at right angles in a flange 2, which surrounds anopening of less diameter than that surrounded by the wall 4. On theother side of the ring the wall 4 extends up wardly in a parallel wall8, which provides an intervening space 5 between it and the wall 4,which is of a tapering form owin to the slight divergence of the walls 4and 8 from the point at which they join. The wall 8 extends to a pointapproximately on a plane with the terminal of the wall 4, from whichpoint it curves outwardly and thence downwardly in an outer flange orwall 6, there being suitable surface between the walls Sand 6 to providea series of oblong holes 7. The space between the walls 8 and 6 isessentially somewhat greater than the cross-diameter of the holes 7,said cross-diameter of said holes being substantially uniform.

Having described my invention, I claim 1. A pipe-coupling ring formedfrom a blank of sheet-steel and consisting of walls surrounding twoopenings of different diameters, the Wall surrounding the opening ofgreater diameter terminatlng in a parallel extension which curvesoutwardly in a third parallel wall or flange, the surface which joinsthe two outermost walls being provided with a series of openings,substantially as specified.

2. As a new article of manufacture, a pipecoupling ring formed from ablank of sheetsteel and consisting of walls 4 and 2 surrounding openingsof different diameters, the wall 4 terminating in a parallel wall 8,said wall 8 extending in an outer parallel Wall 6, the part interveningbetween the Walls 8 and 6 being of suflicient width for the provision ofa series of openings 7, and the said wall 6 lying a substantial distancefrom the wall 8, sub stantially as specified.

In testimony whereof I aflix my signature in presence of two witnesses.
